Electrical Safety
Provisions for an adequate and safe power supply to the fan unit is essential to your safety. Cumberland
recommends that a competent and qualified electrician undertake all electrical wiring. All wiring is to be
installed in accordance with National, State and Local electrical codes. Fans used to ventilate
livestock buildings and other rooms where continuous air movement is essential should be connected to
individual electrical circuits with a minimum of two (2) circuits per room.
We strongly recommend the installation of supplementary natural ventilation as well as a back-up
thermostat. There should also be an alarm system on at least one cooling stage. For connection
requirements, refer to the diagram on the motor nameplate as well as information enclosed with the fan
control being used.
For single phase fans, motor overload protection should be provided for each fan. A circuit breaker or
slow blow motor type fuse must be used. A safety cut-off switch should be located adjacent to each fan.
Contact your local distributor for the correct cut-off switch.
The motor must be securely and adequately grounded. This can be accomplished by wiring with a
grounded conduit or a separate ground wire attached to the motor’s ground lug. Do not attempt operation
unless the motor is sufficiently grounded.
Do not kink power cable and never allow cable to come in contact with oil, grease, hot surfaces
or chemicals.
Remember, electrical safety is your responsibility.

3. Installation
Framing and Positioning
1. Construct the opening frame to the correct size (61-1/4" H x 58" W) as shown in Figure 3A.
Remember, framing must be able to support the weight of the fan assembly. Ensure the load
bearing portion of the bottom sill is rigid and properly supported.
2. When installing more than one fan while trying to maintain 60" centers it is necessary to use one
1" x 4" in the side framing. The cone diameter is normally 65" in diameter but the “Arches” in the side
cone panels can be flattened giving a total of 59" side to side. See tabbed cone panel assembly
on Page 12 for details. If not sure of sufficient clearance, contact your local distributor for more
information. (See Figure 3B.)

Installation of the Fan on a Vertical Plane
1. Position the fan in front of the opening from the inside of the building. Using a minimum of two (2)
people, lift fan housing into the opening.
2. Because of the design and operation of the butterfly flaps it is necessary to mount the fan
vertical regardless of the angle of the wall to which it is mounted. In order to accomplish this it
is recommended that a level be positioned vertical on the housing and shims (furring strips can be
used) be placed behind either the top or bottom mounting flanges until the fan is fully vertical.
(See Figure 3C.) Once you confirm the fan is setting vertical in the opening, fasten flanges to the
rough opening framework with the wood mounting screws provided. Failure to complete this step
can result in insufficient closure of the butterfly flaps. The fan housing should now be flush and level
inside of the framing.

Butterfly Assembly
1. Install the spring clips (12-0457) (2 pieces) as shown in Figure 3H onto the butterfly frame.
2. The V-shaped center bar of the butterfly frame weldment should be positioned vertically, with the
bottom lining up with the slots farthest out on the cone and the top lined up with the slots farthest in
on the cone. This will give the butterfly frame weldment a slight tilt back (~ 1"). This aids the closing
of the butterfly flaps.
3. Use 1/4" x 1-1/4" bolts and nuts to fasten the butterfly frame weldment to the panels. Tighten the
1/4"nuts.Attach thesprings from thedoors tothespringclip andpushtheflaps openandthey should

Motor Mounting Instructions (Single Crated Fans Only)
SUMMARY:The instructionsdescribe how toproperlyinstall the motor on your new 54"Galvanized
Butterfly Damper Fan. Upon delivery of your 54" Galvanized Fan, you will notice that the motor has
been turned around and bolted into location to decrease the width of pallet and maximize shipping
container space. In order to orient the motor properly for fan operation you will need to follow the
below steps
.
NOTE: Motor instructions on this page do not apply to Q skids.
NOTE: Motor instructions on this page do not apply to single crate fan orders prior to December 2012.
Step 1: Figure 3O shown below shows how the motor will look after the fan is installed in the wall of the
building. (Note that two (2) front bolts/nuts hold the motor in place while two (2) rear bolts/nuts are
installed in holes on the same bracket.)
Step 2: Loosen and remove all four (4) nuts and four (4) bolts shown in Figure 3O.
Step 3: Motor should now be free from bracket. CAREFULLY rotate the motor 180° around on the motor
plate so that the centerline of the motor pulley is located over the rectangular slot in the motor
bracket. (Note that the positioning of the holes in the bracket along with the pre-set pulley should
allow the motor to be placed in only the correct position.)
Step 4: Re-attach motor to plate using the four (4) nuts and four (4) bolts previously removed in Step 2.
Step 5: Tighten the four (4) nuts and four (4) bolts to a torque setting of 13 foot/pounds.
Step 6: The belt is tie wrapped to the fan around one of the vertical uprights. Wrap the belt around the
motor pulley, driven pulley and tensioner arm pulley’s.
Step 7: Fan is now ready to be powered on provided the fan is secured to the wall, all applicable safety
guards are installed and the fan has been wired by a qualified electrician.

4. Wiring
Electrical Hook-Up
As previously mentioned, All wiring should be installed in accordance with National, State and Local
electrical codes. A certified electrician should complete this portion of the installation to ensure safety and
that the wiring is correct for the application.
1. First, remove the back cover of the motor exposing the wiring block. (See Figure 4A.)
Figure 4A
2. The motor is designed to use either a solid clamping conduit on the side of the motor or the supplied
wire with a three-prong plug attached. In either case, it is important to attach the ground wire to the
ground lug as depicted in Figure 4A. For correct motor rotation (CCW), the Red wire should be
located on the L2 connection as depicted. If this is not the case, switch the Red and Black wires.
Refer to wiring diagram on the side of the motor for correct wiring for 115V and 230V supply.
3. Fans used to ventilate livestock buildingsor other rooms where continuous air movementis essential
should be connected to individual electrical circuits with a minimum of two (2) circuits per room.
For connection requirements refer to diagram on the motor nameplate. For single phase fans, motor
overload protection should be provided for each fan. A safety cut-off switch should be located next
to each fan. A circuit breaker switch or slow blow motor type fuses must be used. (See Figure 4B.)
3 Phase fans require three (3) pole contactors with overload protection.

5. Operation and Maintenance
Start-Up and Operation of the Butterfly Fan
1. With the fan de-energized, rotate the prop by turning the fan pulley, look for clearance between
the prop tip and the housing. Replace all guards and check all fasteners to ensure they are tight.
When satisfied, energize the fan and make note of direction of rotation. The prop should turn
counterclockwise when viewed from inside the house and the butterfly flaps should open completely.
They are designed to stay open during fan operation and close when the fan is de-energized.
If the prop is turning backwards, the flaps will not open. If this is the case, refer back to Figure 3J on
Page 15 and switch the black and red wires as noted after de-energizing the fan. Re-check the
operation and when satisfied the fan is operating properly, follow the instructions below.
2. Write down the date that the Butterfly Fan went into service and follow the maintenance schedule as
listed below:
a. Check the belt, pulleys and the bearings after every two (2) months of service. The belt tensioner
should be positioned between the 2nd and the 3rd notch as indicated by the mark on the body of
the tensioner. Under tensioning will result in belt slippage, over tensioning will lead to premature
belt and bearing failure.
b. The motor and shaft bearings are lubricated at the factory. The motor bearings should never
require lubrication over the life of the fan. Pillow block bearings should be re-lubricated every
30 operating days and/or after each wash down cycle with three (3) shots of grease or until
fresh grease is seen purging past seal. Lithium or lithium-complex based #2 NLGI grease must
be used. Other types of grease are incompatible with the factory lubricant and will damage
the bearing.
Incompatible grease or lack of service will void bearing warranty.
3. When cleaning the fans, Do Not Spray bearings, tensioner or motor directly with a pressure washer
as this Will lead to premature failure of these components. After cleaning the fan, simply wipe these
parts with a clean rag to remove dirt and debris. Failure to follow these instructions will void the
warranty on these components.
DANGER
Disconnect and lock out all power sources before servicing equipment.
CAUTION
DO NOT use a pneumatic or powered grease gun.

6. Troubleshooting
Troubleshooting Guide
Fan would not Start
1. Check the power supplied to the fan at the point closest to the fan.
2. Check the wiring to the fan.
3. Override the controller (set to manual) and re-check.
4. Contact your Cumberland distributor.
Fan Turns Slow
1. Check the voltage supplied (must be within ±10% if the nominal voltage).
2. De-energize the power and check the wiring at the rear of the motor.
3. De-energize the power, remove the belt and rotate both the motor and fan pulleys. Do they turn
freely? If not, contact your Cumberland distributor.
Fan is Noisy or Vibrates
1.De-energizethefan.Checkfor loose parts,i.e.,bolts,screws,motor,pulleys, prop.Arethefanblades
even? Turn the prop inside of the venturi and look at the blade tips as they move past the same
location. Do they all three appear even? (NOTE: They can be a little different without any problems.)
If they are significantly different contact your Cumberland distributor for more information.
2. Is the noise coming from the bearings? Lubricate per instructions and energize the fan. Did the noise
subside? If not, the bearings are probably damaged and in need of replacement.
Butterfly Flaps do not Close Completely
1. Check vertical alignment of the butterfly frame using a level. If not level, shim the housing out as
described on Figure 3C on Page 11.
2. Check the springs, are they attached? If not, re-attach. Are they stretched and no longer under
tension? Contact your Cumberland distributor for replacements.
3. Check the butterfly flap bushings, are they full of contamination? Rinse with water and remove all
buildup of dirt and contamination. Move the flap by hand until loose and moving freely.
4. Look to see if the flap is bent. With the fan OFF completely close both flaps and look along mating
surface of the butterfly frame. Are all points contacting? If not, bend the flap slightly until all
surfaces contact.
